  • Damping valve, in particular for shock absorbers of vehicles, with adjustable damping force
    Patent number: 10927918
    Abstract: The invention relates to a damping valve, in particular for shock absorbers of vehicles, with an adjustable damping force, in which differently sized outlet openings arranged between an inflow and an outflow can more or less be closed in order to obtain a desired damping effect. To this end, the differently sized outlet openings are more or less sealed off radially by means of a valve slide. In another embodiment, sudden pressure increases in the damping valve are automatically reduced by means of a differential area function. Due to said invention, said damping valve can be produced easily, has low leakage loss, a low tolerance chain and requires little effort for setting the desired damping.
